Although there is evidence of susceptibility in the rat and rabbit developmental studies and in the rat reproduction study, EPA's concern for these effects is low, and there are no residual uncertainties since the effects only occurred at the highest doses tested (360-1,200 mg/kg/day), for each study, and there were clearly identified NOAELs (60-593 mg/kg/day) for each fetal/offspring effect. The thicker the wheat crop and/or the taller the wheat crop, the more force that winds exert on the root anchorage system and the greater the likelihood of lodging. 2.

The finer the spray particle size, the more uptake and suppression youre likely to get. Application of Palidsade or Palisade plus Tilt resulted in numeric reductions in lodging scores at Stillwater, but the result were too variable to result in statistical significance. In adult animals (rats, rabbits, mice, dogs), no systemic adverse effects are seen below the limit dose following subchronic or chronic oral exposure with the exception of dogs. Developmental toxicity was observed in the rat (increased incidence of asymmetrical sternebrae) and rabbit (decreased number of live fetuses/litter and increased post-implantation loss) at the highest dose tested, with no evidence of maternal toxicity observed in either species. We rated plots for lodging at harvest using a 1 10 scale with 0 equaling no lodging and 10 equaling complete lodging. Comments were received on the notice of filing. We conducteda separate trial evaluating Palisade in drought stress environments that was partially funded by Syngenta.
